Standard C Library Functions                       atomic_inc(3C)



     uint32_t atomic_inc_32_nv(volatile uint32_t *target);


     uint_t atomic_inc_uint_nv(volatile uint_t *target);


     ulong_t atomic_inc_ulong_nv(volatile ulong_t *target);


     uint64_t atomic_inc_64_nv(volatile uint64_t *target);


     void *atomic_inc_ptr_nv(volatile void *target);


DESCRIPTION
     These functions enable the  incrementing  (by  one)  of  the
     value stored in target to occur in an atomic manner.

RETURN VALUES
     The *_nv() variants of these functions return the new  value
     of target.

ERRORS
     No errors are defined.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:

SEE ALSO

NOTES
     The *_nv() variants are substantially more expensive on some
     platforms  than  the  versions that do not return values. Do
     not use them unless you need to know the  new  value  atomi-
     cally.
